Yes, in the Admin tab on Server there is an option for schedules and you can simply remove or modify it there
Thanks. Is there a way for a developer (non-admin) to do this so they don’t have to republish the workbooks?
Not exactly sure as I'm the only one who publishes in my organization. I would think there's gotta be a way to give others admin rights. Email firstname.lastname@example.org and they'll be able to say for certain.
Make sure to mark your question "answered" at some point along the way. This helps others know you've found an answer. Cheers.
Here's a screenshot showing you where you can make other users Admins (the link above mentions Site Admins being able to modify schedules).
Hope this helps, take care!
Additionally, when are you are publishing the report as a developer to Tableau server you can set an auto refresh by
"Scheduling and Authentication" button which will be displayed when you login on Tableau Desktop and click on Publish Workbook!
Hope it helps!
